Compounds having an immunizing activity

Abstract

Process for the preparation of new immunizing compounds of 2,6-di[(monoalkylamino)-acetyl amino]anthraquinone, by reacting 2,6 diaminoanthraquinone with a chloracetic acid chloride and reaction of bis-β-halogenoacylamino anthraquinone thus obtained with methylamine or ethylamine. Also disclosed are compounds thus obtained or acid addition salts thereof, pharmaceutical compositions and utilization of said compounds as immunizing drugs.

I claim: 
     
       1. A method for the treatment of a mammal to achieve immunizing activity, which comprises administering to such mammal an immunosuppressive amount of a compound of the formula ##STR5## wherein R 2  is methyl or ethyl, or an acid addition salt thereof. 
     
     
       2. A method according to claim 1 wherein the compound is 2,6-bis-[(methylamino)-acetylamino]-anthraquinone. 
     
     
       3. A method according to claim 1 wherein the compound is 2,6-bis-[(ethylamino)-acetylamino]-anthraquinone.
